To all 'whom it may concern Be it known that I, HOWARD W. REY-` NoLDs, acitizen of the United States, residing at4 Chicago, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Water-Meters, of which the following isa specification.I

My invention relates to improvements in water meters and particularly)to water meters of the disk piston type. l

A main object of the invention is to provide meansin a water meter whichwill serve as a fish trap and also as a trap'for Asand and sediment, andan lobject servient, thereto is" to provide a screen which can bereadily removed for cleaning purposes.

Another object of the invention is to provide means whereby the diskpiston is strengthened so as to minimize the. chances of warpingoccasioned by the varying temperatures vof the water passing through themeter. f

Still another object is to provide the strengthening means for thedisk-piston of a metallic' plate having corrugations tending from thecenter of the disk but not rafdally thereof, so as to provide vaconstruction wherein the valve is strengthened to a greater degree thanwould be the case if the valve were strengthened along radial lines. Afurther object of the invention.v 1s to' provide a means whereby thewater passing to the gearing chamber may be filtered so as to serve as alubricant for the various parts of the gearing. y

With the foregoing. as well as additional objects, such as willhereinafter appear,` .in View, the invention resides in certain details`.of construction, combinations and arrangements of parts as illustratedin accompanyingrdrawings, wherein: water meter partly in elevatiombutpartly iii/vertical section; Fig. 2 is a plan view of the lower sectionof the meter;` Fig.. 3 isa view ofthelower section of the meter, partlyin elevation and partly in section; Fig. '4 is a side elevation of thedisk; Fig. 5 is a plan a modied form of closure for the gearingychafmber Fig. 8 is a fragmentary view of the modied form of gearingchamber clo- I shown in Fig. 7, and Fig. 9 is a detail igure 1 is a viewshowing my improved.

corrugations of the disk cross sectional `view `on an enlarged scaletaken on the line 9 9 of Fig. 7.

Referring specifically to the drawings wherein .like referencecharacters designate like or-similar parts, the water meter chambercomprises an .upper section A and a lower section B which are securedtogether by bolts 1 passing through `apertures of anges on the sectionsA and B.

` The disk `piston is shown at C and is contained within a measuringchamber formed threads which are engaged at 12 by screw threads o f abearingy or socket member' 13.

A bearing or socket member 14 is mounted in the section 4 by theengagement of screw i threads thereof at 15 with screw threads of anupwardly extending wall 16. rlhe ball in order to mount the sections.17, the bear'- ings 13 and 14v are provided which have spherical seatsat 18 to receive the ball. Openings 19 are provided through the bearings13 and 14. r v

rihe piston proper. comprises a disk like element 20 which is fastenedto the sections 17 by means of the piston shaft 21. This shaft 21 has anenlargement, 22 which is lo-A cated within a recess of one section 17and this shaft is also provided with screw threads on which rides anut'23. This nut extends into a recess of the other section 17 'V anditserves as a `means for fastening the sections 17 together so as toclampthe disk 20 therebetween. The central opening of u the disk isenlarged with respect to the shaft 21 and into this opening extendabutting hubs 24 integral with the sections 17. v

it is, as stated, a yparticular object of this invention lto provide' aneffective means whereby the chances of the diskv 20 warping-whensubjected to use inconnection with water of varyingf temperatures areminimized To this end, the disk has two similar casing sections .20apreferably vof hard rubber'between which embed a thin metallic (li-likereinforcing elem Patented Apr.;v i8, 19in. Application led November 19,1914. Serial No. $72,999..'

As best seen in Fig.6, this elementi is corrugated and the corrugations,o r ribs which vare designated 25, are widest at a point 1ntermediatetheir ends, preferably the cen'v ter and transversely of the yelement25. The corrugations 25 are curved or bent so that when in place in thedisk, as seen in Fig. 5, they will not extend radially of the diskcenter. 1t will be noted, that a number of these elements crosses eachradialy line that may be drawn from the center of the disk. Thus at noportion of the disk can a radial line be drawn without crossing aplurality of the corrugations 25a. Therefore, the disk is strengthenedto a much greater degree'th 'would be the case if strengthening elementsextended radially from the disk-.centen There are no direct lines offlat surfaces throughwhich bending or `warping can effectively takeplace. If warping tends to take place, the corrugations combat it'tosuch an extent as to make it practically impossible. In thisconstruction of disk, the resistance varies at each point of thesurface. i The sections 2()a have ribs or flanges 20b atl their innerandouter edges to protect the edges of disk 25. Openings25b are providedin disk 25 and the sections 20 are clenched therein.

Means is provided below the measuring chamber to Iilter the water whichpassesY through the same. To accomplishthis end, a plate 26 is removablyfastened by setscrews 27. to a flange 28 of the lower jsection B.-Extending inwardly and integral with the plate 26 is an annularextension or ring 29 which is preferably cut away above its center to'provide a space 30 through which' the water passes after entering thescreen or trap meansnow to be described. A trap or basket 31 which maybe made of any suitable material, for instance, screening so B afterremoving the set-.screws -27.

owmgas to be foraminous is fastened to the ring 29 and has a portionlwhich extends over a bead 32 on the ring 29 and beyond which bead.,said portion `is clenched into a groove 33 of the ring.

The water entersthe chamber B through an inlet 34and then flows aroundthe trap cut away portion 30. As the water-flows lthrough the trap,f'.all sand and sediment is screened therefrom and in addition `fish. whichmayflow in with the water are captured in the trap.' At suitable times,the plate 26 may be detached from the' section y After removal ofthe'plate 26athe same v,may be inverted so that the deposit within thetrap 31 may be' emptied throughv the-'cut-awa-y are in place, 'the waterafter through thev 'trapows into the water Vet A` 'chamber causingoscillation ,of the *pis-5' toa C andjp'g-then owiag rointhe chambertimes.

As is usual in water meters, the chamber,

-here comprising the sections A and B will,

for the most part, be full of waterat all water as a lubricating medium,the follow- 'ing construction is provided. An annular flange integralwith the section A extends interiorly thereof above the measuringchamber 3-4 at 37 and fastened thereto by means ,of vset-screws 38 is abearing' plate `39. This plate 39 forms the bottom wall of a gearingchamber which is completed by a portion 40 of' theouter wall'of chamberA- andby a wall 41 adjacent and interiorly of the top of'chamber'A. Thisplate 39 serves as a. bearing for the gearing within the chamber whichis shown at D inasmuch as In order that If may utilize lthe t miA shafts42 of the gearing may have bearing f in recesses 43 formed in the plate.A ange 44 is provided on the plate to extend within the iange 37 toassistin positioning the p plate for fastening. Extending ydownwardlyfrom and integral withthe plate 39 is a hub 45. A shaft 46 of thegearing is mounted in a bore Lprovided Iin the hub 45 and on the hub 45is mounted a guide member 47. Below the guide member 47 a split springring48 surrounds'a recess in the hub to in turn actuate the register inthe up- .permost portion E' of the section A.

` Above the guide member 47,`and mounted on the hub 45, is a foraminousdisk 51 which sets in a recess 52 of the plate 39. This disk 51'istightly fastened in" therecess by means of a nut 53 which' rides onscrew threads of the hubV 45 at Av recess l 56 is provided in plate 39and therein is contained suitable \iiltering material, for instance,felt,` wicking or other fabric, and communicating with the recess 56 areopenings or ports 57, which orts alsocommunl- 'cate with the interior vothe gearing chamber. Water within the chamber A will flow through theforaminous disk 51, thence through the filtering medium, beingthereby'iltered, and the filtered waterwillthen iow through the ports57"into-the gearing chamberfwhere it acts as a lubricant for the variousgearing-elements. l"Undue wear of the gearing-elements will bepreventedin-v as'much as the sediment `-orgsolid matterv is filtered from, thewaterby thev means;` mentioned before 4entering the' gearing chamber.The water cannot ow above the gearist ing chamber in view of theprovision ofv wall 41.

A modification of the bearing disk 39 is shown in Figs. 7 and 8 wherethe disk is generally designated 58. v` Except for-the fact that the hubof the disk 58 is modified, the construction of the disk is identicalwith the construction of disk 39. In this modiied form, the hub isdesignated 59. The foraminous disk is designated 60 and 'has a collar 61which surrounds the hub 59 and has inwardly extending spring lugs 62which i y may vary the det'ails of construction without departing fromthe spirit and scope of the invention. x
